Horizon Minerals Ltd (ASX:HRZ) has doubled down on nickel sulphide mineralisation at two of its nickel prospects within the Greater Boorara-Cannon project area in WA.
The resources stock has received the final single-metre drill assays from the Euston and Blair North targets, paving the way for future nickel exploration in the region.
At the Euston prospect, two reverse circulation (RC) drill holes returned encouraging assays including 2 metres at 2.21% nickel, 765 parts per million (ppm) copper, 324ppm cobalt and 0.76 g/t platinum-palladium from 161 metres and 4 metres at 0.64% nickel and 321ppm copper from 180 metres.
Meanwhile, 900 metres to the northeast at Blair North, one RC hole also confirmed the initial composite assay, returning 2 metres at 2.68% nickel, 0.9% copper, 440ppm cobalt and 0.71 g/t platinum-palladium from 176 metres.
Thanks to the findings, roughly 1 kilometre of follow-up RC drilling is planned at Euston and Cannon this year.
What about the other prospects?
Beyond Euston and Blair North, Horizon also conducted three downhole electromagnetic surveys at the Golden Ridge prospect.
Encouragingly, three off-hole conductors were observed and specialist consultant Southern Geoscience has recommended several follow-up drill holes to test the property in FY23.
Over at Yarmany, three wide-spaced, deep RC holes were drilled under the prospective nickel laterites, highlighted during aircore drilling last year.
Here, Horizon uncovered a fertile komatiite unit, with further analysis and follow-up drill planning underway.
In addition, first pass auger sampling — comprising 972 shallow holes — has been completed across Yarmany, with all samples submitted to LabWest for multi-element ultrafine analysis
More results are expected before year’s end, while drilling is scheduled at Golden Ridge and Yarmany early in 2023.
Grassroots exploration “continues to deliver”
Commenting on the nickel exploration success, Horizon managing director Jon Price said: “It’s very encouraging to see confirmation of nickel sulphide mineralisation at Blair North and Euston and we look forward to further drilling success in this highly prospective area.
“The results from the downhole electromagnetic survey and geoscientific analysis at Golden Ridge have also demonstrated the potential of the area to host significant new nickel sulphide mineralisation.
“The company’s grassroots exploration program is continuing to deliver quality results in gold, nickel and rare earths as we test high priority targets across the core Greater Boorara-Cannon, Lakewood, Yarmany and Binduli project areas with further results expected in the current quarter.”
